linux wireless bridge

It is particularly worth mentioning that there are many things worth learning about Linux bridge. Here we mainly introduce Linux bridge, including Linux bridge. Linux

Host-only and bridge communication between host machines and linux in Vmware: my host is called a host machine in this article, in vmware, linux is called linux. in this article, the host-only mode is used to ping linux, but in host-only mode,

There are five hosts. One of the hosts is installed with Linux and the bridge module is installed. There are four physical NICs that connect other hosts in the same network segment. We want it to become a bridge and forward data packets between the other four hosts (IP addresses are 192.168.1.2, 192.168.1.3, 192.168.1.4, and 192.168.1.5 respectively. In addition,

Linux Bridge is a core-supported bridge device that enables simple switch functionality. Now the demand is to listen to the cloud platform, the cloud host all the traffic. We're using bridge, not a powerful software device that uses vswitch. By accessing the information http://backreference.org/2014/06/17/port-mirrorin

Use the bridge to connect to the Internet, you need to configure the Linux system IP, the following steps: 1, in the command line mode or desktop access to terminal mode, find/etc/sysconfig/network-script/ifcfg-eth0 file; 2, using VI to open the file VI ifcfg-eth0, note that some Linux system this file may not have ifcfg prefix. 3, need to change: Bootproto=sta
